This table contains the deadband values for set point adjustment at 10% and 90% of the selected scale. For adjustable deadband the lower value corresponds to the deadband spring totally released and the higher corresponds to the deadband spring fully tensed . For other set points the deadband value can be calculated by linear interpolation between the values at 10% and 90%. 2) For RPPE6 only. 3) For RPPE8 only. 2015-05-26 Design and specifications subject to change without notice 1) www.baumer.com Data sheet A32.11 Page 3 / 5 RPPE6 - RPPE8 Industrial pressure switch, explosion proof with high overpressure resistance Dimensions (mm) Set point adjustment Differential adjustment 56 (3x) Ø 9 on Ø 222 86 20 Ø 194 12 0° 139 120° 116 RA EE x d II C T 0° 6 12 Cable gland not mounted 121 Weight : 4.4 kg Pressure range code : 204 - 205 - 206 - 210 Weight : 2.4 kg 50 63 Pressure range code : 201 Weight : 2.4 kg flats 26 SW 26 G1/2 male 1/4NPT female G1/2 male Ø44 2015-05-26 Design and specifications subject to change without notice Ø60 24 flats SW 24 www.baumer.com Data sheet A32.11 Page 4 / 5 RPPE6 - RPPE8 Industrial pressure switch, explosion proof with high overpressure resistance Ordering details RPPE6 - RPPE8 RP Model Industrial pressure switch Approvals Explosion proof high over pressure Sensing element Diaphragm (Perbunan ®, code 201) Diaphragm (Stainless steel, range 204 to 210) Type of micro switches 1 SPDT standard changeover switch 2 SPDT standard changeover switch 1 SPDT hermetically changeover switch 2 SPDT hermetically changeover switch 1 SPDT ultra sensitive changeover switch 2 SPDT ultra sensitive changeover switch 1 SPDT hermetically, ultra sensitive changeover switch 2 SPDT hermetically, ultra sensitive changeover switch 1 SPDT gold contact changeover switch 2 SPDT gold contact changeover switch 1 SPDT tropicalized changeover switch 2 SPDT tropicalized changeover switch Process connection G 1/2 male (standard) 1/2 NPT male 1/4 NPT female PE . – xxx / RP PE – 6 8 Deadband Adjustable Adjustable Adjustable Adjustable Fix Fix Fix Fix Adjustable Adjustable Adjustable Adjustable A B C W E F D V M K N T 3 6 8 Pressure range (bar) Pressure range (kPa) 1) -1 ... 2.5 1) -100 ...250 0.5 ... 10 2) 50 ...1000 2) 3.5 ... 25 2) 350 ...2500 2) 5 ... 50 2) 500 ...5000 2) 2) 0.2 ... 4 2) 20 ...400 Options to be added behind the / (see example below) 1) RPPE6 only 2) RPPE8 only . 201 204 205 206 210 / Ordering example with options RP PE – 6 A 3 . 201 / 0407 _ 9941 Industrial pressure switch Explosion proof Diaphragm Perbunan 1 SPDT standard changeover switch Design and specifications subject to change without notice Process connection G 1/2 male Pressure range -1 ... 2.5 bar Option : Mounting on 2" pipe 2015-05-26 Option : Stainless steel tag plate and wire www.baumer.com Data sheet A32.11 Page 5 / 5
